In Germany-November 4, 1937 8 Claims. (c1. 198--.-165) The present invention relates to the arrangement of the elevator conveyer in harvesting, especially mowing and binding machines and particularly to a method of mounting and'sus- '3 pending the upper inclined conveyer to the main frame of machines of the type set forth.

An object of the present invention resides in the provision of suspension means for the upper inclined conveyer in mowing and binding machines whereby the passage formed between the upper and lower conveyeris open on one side to provide for any length of harvested goods and whereby no structural elementsare needed which project beyond the. width of the conveyors and unduly increase the space requirements of. the

machine. With the construction according to the present invention an unobstructed passage of the mowed material from the substantially" horizontal platform up to the binding table is to assured. and the .totalwidth of the mowing'and binding machine is held at a minimum so that it can be moved through narrow streets .and

congested areas without difiiculty.

An obje t of the present invention resides in 3:51 the provision of a support system, for the upper elevator of mowing and binding machines'jand the like whereby one bearing of the upper roll of said elevator is supportedin the front head piece and the lower partof the elevator is movably 35) supported in a slot of the elevator wall andthe elevator is swingably supported by means of one or a plurality of Outriggers the ends of which outriggers are provided with flanges or the like which carry the other bearing of the elevator 313 ml! and also the rods for positioning the elevator. The outriggers may be rigidly connected with the front head"piece,-withthe elevator wall, with the .main frame or with another suitable part of the machine. I

A further object of the present invention 'resides in the provision of a support for the upper elevator in mowing and binding machines or the like whereby the upper shaft or roll of the ele- 45 vator is utilized as outrigger. Thereby one end of the upper shaft rests in broad bearings of the front head piece and the other end rotates in a guide bearing which is supported by suitable struts. 5n Further and other objects of the present invention will be hereinafter set forth in the accompanying specification and shown in the draw ings which, by way of illustration, show what I now consider to be a preferred embodiment of my 55 invention.

Figure 4 is a part sectional front view of a 'modified elevator conveyer support structure ac- 10 cording to the present invention. 1

Figure 5 is a top view of the structure shown in Figure 4. r

Like parts are designated by like letters in all figures of the drawings.

Referring more particularly to Figures 1 to 3, a designates the main frame "of the machine to which the platform conveyer b and the lower elevator conveyer o is mounted. The upper roll g;of the upper elevator conveyor 1 rests with one end in the. front head piece h; the lower end of the upper elevator conveyer is movably connected with the elevator side wall 1. by means of a peg s To. the head part 71. a tubular outrigger 2'- is connected whiclr1hi v extends over the. whole width of the elevator.

The free end of outrigger i carries a flange ,k to

which the outer bearing 1 for the upper elevator roll g is connected. The upper elevator f is swingably hun'g in between the front head piece h .80 and the flange 7c of the outrigger and is also suspended by means. of a link 0 which hangs in a slot, m of the flange hand is hooked to the ear piece p which projects from the lower part of theside cover platet' of the elevator. A flange 35 q is provided on the tubular outrigger z to which flange the lower ends of the connecting means or tie 'rods 47 areconnected; the other ends of said tie rods are connected with the head piece it so that the tie rods r prop the outrigger against the head piece. By changing the aotive'length of the tie rods r, forexample, by the manipulation of the fastening nuts q and/or h the position of the outrigger 2' and thereby of the upper ele- 45 A cantilever member u may be provided extendg5 ing through bearing member 1) and supporting bearing 27.

In both embodiments of the present invention the harvested material is transported by means of the platform conveyerb' into the space in between the elevator conveyers c and f and is transported by the latter in a continuous and unobstructed flow towards the binding table. The upper elevator f swinging about its upper support and being guided by the slot S in wall t automatically adjusts the space in between the elevators c and j to the volume of the harvested material. The upper end of the link m'oves in slot m of flange It so that'there is no obstruction to the swinging motion of the elevator 1.

With the outrigger or cantilever suspension construction for the upper elevator according to the present invention all obstructions to the free passage of long harvested material which may project far out of the rear side of the elevator are definitely avoided. Furthermore the lower part of the elevator does not take part in the support of the upper part. The position of the free end of the outrigger and thereby of the elevator can easily be adjusted. The elevator can easily be made swingable about its upper roll whereby adjustment of the elevator according to the volume of the harvested material is conveniently accomplished.

While I believe the above described embodiments of my invention to be preferred embodiments, I wish it to be understood that I do not desire to be limited to the exact details of design and construction shown and described, for obvious modifications will occurto a person skilled in the art.

I claim:

1. A suspension system for the upper inclined conveyer in harvesting machines and the like having a main body, saidsystem comprising an outrigger having one end connected in cantilever manner to said main body, said outrigger swingably carrying said conveyer.

- 2. A suspension system for the upper inclined conveyer in harvesting machines and the like having .a main body, said system comprising a tubular outrigger having one end connected in cantilever manner to said main body, said outrigger swingably carrying said conveyer.
